Questions & Answers about Não acho que o preço seja injusto.
Why do we use seja instead of é in this sentence?
Because the sentence starts with Não acho que (I don't think that). While expressing a positive opinion like Acho que... uses the normal indicative mood (é), negating that opinion expresses a level of doubt or denial. This triggers the present subjunctive mood, making the verb ser become seja.
If I wanted to say 'I think the price is not unfair', would I still use seja?
No! If you move the não to the second half of the sentence, it becomes Acho que o preço não é injusto. Because you are now starting with Acho que (a positive statement of opinion), you go back to using the normal indicative mood (é). The subjunctive is only needed when the verb achar itself is negated.
In English, we often drop the word 'that' and just say 'I don't think the price is unfair'. Can I drop que in Portuguese?
No, in Portuguese, the conjunction que is mandatory when connecting these two clauses. You cannot skip it, so saying Não acho o preço seja injusto would be grammatically incorrect.
Why is the verb ser (seja) used here instead of estar (esteja)?
